利用维格纳方法实现对数字信号进行时频分析处理的功能(Wigner method implementation using digital signal processing functions time-frequency analysis)

遗传算法和神经网络混合编程，可用于优化计算，仅供参考(Genetic algorithm and neural network hybrid programming, can be used to optimize the calculation, for reference only)

描述函数法非线性系统分析实例，已经测试可直接在matlab中打开并运行。(Nonlinear system analysis function method described examples have been tested directly in matlab open and run.)

CARS变量选择方法能够在一定程度上克服变量选择中的组合爆炸问题，筛选出优化的变量子集，提高模型的预测能力( Competitive Adaptive Reweighted Sampling method for variable selection.)

水下通信环境下，4FSK调制解调代码及bin文件,(4FSK modem code and the bin file)

说明：  计算图像的偏移量，用于图像间没有旋转的图像配准(Offset images are calculated for the image registration)

这是简易的ASK信号调制，把文件放入matlab的文件库中，通过在matlab的命令窗口直接调用功能函数并运行，可以直接看到仿真结果。(This is a simple the ASK signal modulation, the file into Matlab file library, call function directly in the Matlab command window and run the simulation results can be seen directly.)

This software implements the touch-expand algorithm and demonstrates how it can be applied for shape-from-oriented points reconstruction. The algorithm and its application were suggested in:

结合上传的LMFnlsq2testPDF.rar文件，可以轻松的明白本程序的实现步骤以及编程思想。(Combination of upload LMFnlsq2testPDF. Rar file, can easily understand the program implementation steps and the programming ideas.)
